Winery Pumps for Must, Lees, Pomace and Wine Transfer
Application-focused progressive cavity and centrifugal pump selection for winery products ranging from clear wine and juice to viscous, solids-bearing must and lees.
Match the pump to the product and the duty
Must, lees, pomace, juice, finished wine and cleaning solutions do not behave the same way. Selecting a winery pump only by connection size or motor horsepower can lead to poor flow control, product agitation, plugging, premature wear or difficult cleaning. ACCA starts with the actual fluid and system conditions.
Progressive cavity or centrifugal?
Progressive cavity pumps are commonly considered when the product is viscous, contains pumpable soft solids, requires positive-displacement flow or benefits from controlled low-speed transfer. Flow is approximately proportional to speed, subject to pressure, viscosity, wear and internal slip.
Centrifugal pumps are commonly considered for clean, low-viscosity liquids, circulation and higher-flow transfer at moderate head. Their performance follows the system curve, making correct impeller, speed and operating-point selection important.
Neither technology is automatically better for every winery process. The correct choice depends on product properties, suction conditions, required flow, discharge pressure, cleaning method and the complete operating range.
Common winery pumping duties
Useful for viscous and solids-bearing winery products
A progressive cavity pump moves product through sealed cavities formed between a helical rotor and stator. The positive-displacement principle supports controlled flow over a useful pressure range and can accommodate a broad range of viscosities when the pump and inlet are sized correctly.
A practical choice for many clean-liquid duties
For low-viscosity juice, wine, water and compatible cleaning solutions, a centrifugal pump may provide a simple and economical transfer option. Selection should confirm the required flow and total dynamic head rather than relying on pipe diameter alone.
Specify sanitary and food-contact requirements
“Food grade,” “sanitary” and “CIP capable” are configuration-specific terms and should not be assumed from the pump type. Identify any required sanitary fittings, documented surface finish, food-contact elastomer compliance, stainless-steel wetted components, drainability and cleaning procedure before quotation.
ACCA can review available configurations against the information supplied. The winery and its process engineer remain responsible for validating the selected equipment against facility standards, cleaning validation and applicable regulations.
What ACCA needs to recommend a winery pump
Replacement pump or parts request
For an installed pump, include the nameplate, manufacturer and model, serial number when available, current speed, operating duty and photos of the connections and base. For parts, add any rotor, stator, seal or assembly numbers.
Pumps and replacement components
ACCA supplies progressive cavity pumps, centrifugal pumps and progressive cavity pump replacement parts for industrial applications. Our objective is to identify a practical configuration based on the product, process duty, materials and installation—not simply substitute a model number without reviewing the application.
Winery pump questions
Can one pump handle must, lees and finished wine?
Possibly, but the full operating range, solids, cleaning requirements and connections must be checked. A pump optimized for thick lees may not be the most efficient choice for every clean-liquid transfer.
Are progressive cavity pumps low shear?
They are commonly selected for controlled, relatively low-shear positive-displacement transfer. Actual product impact depends on pump size, speed, geometry, system restrictions and operation.
Can ACCA provide sanitary or food-contact configurations?
Available materials and configurations vary. State the required material certificates, elastomer compliance, surface finish, fittings and cleaning method so ACCA can determine whether an appropriate configuration is available.
What information is needed for a replacement pump or parts?
Provide the existing manufacturer and model, serial number when available, nameplate and installation photos, current duty, product, flow, pressure, temperature, materials and known component numbers.
Need a winery-process pump?
Send the product, flow, pressure, solids, viscosity, temperature, cleaning requirements or existing pump nameplate.
